Little changed

More than half of the S&P 500 companies have reported third-quarter financial results so far, and while more than 70% have delivered earnings above Wall Street's estimates. The dull results have pushed investors to the sidelines. In fact, all three indexes posted their second weekly loss in three weeks. A stronger-than-expected report on U.S. economic growth was encouraging, but a reading on consumer sentiment fell short of expectations. Apple reported Q3 results that missed expectations, as iPad sales came in lower than forecasts.
